RAILROAD-TRACK-WEEDING MACHINE.

Application filed July 31, 1923. Serial No. 654,938.

T 0 UU who/n 'it 212mg/ concern:

Be it known that I, AUGUSTE Soiiiincnzifzn, citizen ot Switzerland, residing at Renens` near Lausanne, Switzerland, have invented certain new and useful Improvements iu Railroad-Track-feeding Machines, of which the following' is a specification.

In railroad-track weeding-machines known heretofore there was a plough attached to a railroad car and no provision was taken to adapt the apparatus to the variable width ot the embankments or to avoid obstacles such as signaland telegraph-posts and the like.

In the weeding-machine according to the present invention the defects mentioned have been taken into consideration. The plough is movable in a vertical sense being supported by a parallel-lever connection pro* `iecting transversely to the rails from a truck which can be moved transversely to the rails. The plough is suspended vertically by elastic members so thatl it can pass around obstacles projecting above the ballast.

In the accompanying drawing which rep resents one embodiment of the invention, Fia. 1 is a plan with the apparatus in operative position, the inoperative position being indicated 'by interrupted` lines, Fig. 2 is a side elevation and Fig. 3 a front elevation.

On truck not shown, charuiel-irons a are arranged transversely so as to torni the path ot' a trolley b which is moved from a nictoi', not shown, by means ot an endless chain passing over the chain pulley d mounted on the channel-irons and attached to the trolley. A vertical pivot pin e is rotatably incunted on said trolley and two parallel levers f are hinged with their one ends to .Laid pin c and with their other ends to a .sleeve g on a pin la which is parallel to pin c :and tast to one end ot' plough-blade h An adjusting ring 0 prevents said pin 'from slipping out of said sleeve. The other end of the blade is suspended by means ot springs to the truck. These springs will maintain the blade in its normal working position shown in Fig. 1, while the parallellover connection kept suspended by a cable attached to the truck, which cable provides for the necessary tractive force for pulling the plough through the ballast, said lever-connecting being free to swing on the pins g whenever a sleeper projecting from the track more than normally or any other obstacle would obstruct the path of the plough.

Owing to the parallel-lever-connection c, 71., f, the plough is adapted to follow the uneveness of the embankment and may be adjusted in a vertical plane. The amount to which the plough extends to the outside ot the rail-track and which determines` the width 01"' the weeded surface may be controlled by moving the trolley on the truck.

Having now fully described my invention and the manner to which the same is to be performed, that which I claim as new and wish to secure by Letters Patent is:

l. In a weeding machine, guide rails, a carriage mounted to travel between the guide rails, a parallel lever device adapted to swing in a vertical plane, a vertical pin on the carriage pivotally supporting the inner end of the lever device, and a plow connectedwith the outer end of the parallel lever device.

2; In a weeding machine, track rails, a carriage mounted for sliding movement between the track rails, an upright pivot pin carried by the carriage, a parallel lever device pivotally connected at one end withv said pin, a sleeve connected with the opposite end ot the parallel lever device, and a plow supported by said sleeve.

3. In a weeding machine, track rails, a carriage mounted tor sliding movement between the track rails, an upright pivot pin carried by the carriage, a parallel lever device piif'otally connected at one end with said pin, a sleeve connected with the opposite end of the parallel lever device, a plow, and an upright pin carried by the plow pivotally received in the sleeve and permitting swinging movement o't the plow in a horizontal plane.
